I am horrified by this but Dr Google tells me that the circulation of offensive material at work can be considered misconduct. I suppose if your DD were relaxing with 'Ku Klux Klan News' or 'Penthouse' I would support something being done about that.

From what I remember it's not too bad a book but the cover is quite loud on my copy with a sex doll face and bright colours. It depends where she works as to whether putting a cover over it would be polite if she is public facing but they ABU to tell her she can't read what she wants if she offered to cover it!

Unbelievable! I would look for another job and ignore the order. I'm all for sensible rules, but that is nothing to do with the work, and the management shouldn't be catering to the most unreasonable wishes of its staff.
